Calcined bauxite aggregate possesses a series of good performances. For instance, the amount of high alumina is high while the amount of iron is low. What’s more, its hardness and refractory temperature is high while the coefficient of thermal expansion is low. In addition, the thermal properties of calcined bauxite aggregate is pretty stable.

General Description of Calcined Bauxite

Bauxite is earthy mineral, which main composition is alumina, the hydrated alumina with little impurity. It usually takes the color of white and grayish white. Some bauxite takes the color of brown yellow and light red due to the composition of iron. It is extremely hard for bauxite to melt. What’s more, bauxite can not insoluble in water, but it can dissolved in sodium hydroxide solution. The definition of bauxite various from country to country, which is related to the different national resources amount and industrial demand. In China, bauxite refers to the mineral in which the amount of alumina is over 40% and A/S over 2.5.
